Hey all, never posted on here before and I pretty much know next to nothing about audio pairing or set-up so go easy on me. I have a piar of KG 3.2's that I bought off a buddy in college for like $30, along with a little radio/3 cd player/cassette player unit that he used to power them. I've been using that thing for a while, but I think it is time for an upgrade. I have a budget of around $250, and would like to get an amp that can power them and hook up to both the tv and play music from a computer. Any advice would be appreciated, since I pretty much don't know where to start! Thanks, Keegan
